The inventor claims:

1. In a shower head: a body forming a iiuid chamber, said body having an inlet opening at one end, and a flange forming a uniformly diverging outlet opening at the other end, said flange having similarly diverging annularly arranged substantially longitudinally directed ribs terminating short of the end of saidoutlet; a

first spray member of flat annular form having a peripheral tapered edge cooperable with said outlet opening and engageable in a wedging relation with said ribs of said outlet opening; a supplemental spray member telescoping in and immovably secured to said firstspray member and having peripheral serrations forming. with saidfii'st spray member an inner annular series of spray openings of invariant size; and means movement .with respect to said supplemental J spray member for moving said spray members together and having a threaded shank portion cooperating with'said. threaded portionof said Wallmea'nss 2. In-a shower head: albod'y forming a fluidchamber, said body having. an inlet opening at one end, and a flange forming a uniformly diverging outlet opening at the other end, said 4 flange having similarly diverging annularly an ranged substantially longitudinally directed ribs terminating short of'the end of said outlet; a first spray member of flat annular form having a, peripheral tapered edge cooperable with said outlet opening and engageable in a wedging re-' opening, including perforated wall means carried by the body and having a threaded aperture, an adjusting screw having a head exterior of said supplemental spray member and a threaded shank portion extending therethrough and 'engageable with said threaded aperture, and a snap ring engaging the screw on the interior side of said supplemental spray member for securing said adjustingscrew against longitudinal movement with respect to said inner spray member.
